Ok, this is not a very good one, but whatever. When Shrek is at the potion thing, he gets dressed up as one of the workers. to one of the other workers, he says, TGIF which stands for thank god its friday. the next day once shrek and donkey have transformed, they're at the bar. then, puss says "i hate mondays." so, there are no weekends!! that would really suck!
